Correct option (C) both of these (A and B)
Explanation:
Grignard’s reagent reacts with primary or secondary amines to give alkanes but fail to react with tertiary amines due to lack of hydrogen on nitrogen.
R-MgX + R-NH₂ → R-H + Mg(NHR)
The reaction between ethanol and Grignard is shown below:
CH3CH2OH + R’MgX → CH3CH2O-(MgX)+ + R’-H
